FASTENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 24:8,359, dated October18, 1881.

(ModeL) T0 atlwhom it may concern Be it known that I, GARY B. SMITH, acitizen of the United States of America, residing at Cleveland, in thecounty of (luyahoga and State of Ohio, have invented certain new anduseful Improvements in Sash-Fasteners; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, refere nce being had to the accompanyingdrawings, and to letters or figures of reference marked thereon, whichform a part of this specification.

This invention relates to that class of sash fasteners or locks forpreventing a sash from being opened from the outside.

My invention consists in the novel construction and combination ofparts, as will be hereinafter more fully set forth and specificallyclaimed.

In the annexed drawings, Figure 1 is a perspective view of thesash-fastener applied to the meeting-rails of the sashes. Fig. 2 is avertical sectional view of the same. Fig. 3 is a side elevation. Fig. 4is a perspective view of the slotted rail-piece of the upper sash. Fig.5 is a perspective view of the overlookingpiece of the rail of the lowersash and Fig. 6 is a perspective view of the gravity locking means.

The letter A represents the section of the lock to be attached to theupper surface of the upper or meeting rail of the lower sash. Itis castinone piece, and is formed with the base portion, a, to rest on therail, and the upright portion 1), provided with perforated lugs c and c,from the under parts of which extend downward the interlocking arms 01and d, which form a plane on the outer face, and are inclined from thepoints to the base on the inner face, forming a half-wedge. The innerface of this section iseut away at the base, and is formed with avertical recess, 0, extending from the base part way to the top. Thearms 0 and 0 have a pivot-hole through them for the purpose ofreceivingthe bolt of the locking means, and the base-plate is provided withcountersunk screw-holes, so that it may be screwed fast to the rail.

The base-plate may be formed or provided with a finger-lift,substantially as indicated by the dotted lines in the drawings.

The letter B represents the section of the lock to be attached to thelower rail of the upper sash. It is cast in one piece and formed withthe horizontal base-plate], to rest on the sash-rail, and the upright g,having the central mortise, h, and the upright exactly fits into thespace in section A, between the inner surfaces of the upright and theinterlocking arms.

The letter 0 represents the automatic looking plate and hook, formed tofit about the sections A and B when they are .in contact, and isprovided on its inner side with a lug, i, and also has a thumb-piece,7c, substantially as seen inthe drawings. This locking device is securedin place between the arms 0 c of section A by a pivotal bar or rod runthrough the hole in the base of the thumb-piece. It is also providedwith side flanges, l, lapping the wedgeshaped arms and standard portionof the sections.

The object of the downward extending wedge-shaped piece in section A isto fit over the wedge of section B, and thus present them in contact forthe action of the automaticlocking hook and clasp, substantially as seenin Fig. l of the drawings.

The device is applied to the sash by screwing section A, with thelocking means attached, to the upper rail of the lower sash and sectionB to the lower rail of the upper sash, so that the standard of thelatter will fit and register in the space behind the extending arms ofthe former, and the lug of the locking means register in the centralslot and recess of the sections, falling therein by gravitation when therails meet with the sashes closed, and thus securely lockin g themtogether.

To release the sashes from the operation of the lock pressure is appliedto the thumbpiece, which draws the lug from the slot and recess, andthen the sash may be raised, as in ordinary cases.

It is obvious that slight changes may be made in the constructionwithout departing from the spirit of the invention.

It will be observed that when the rails of the sashes are broughttogether and the fastener is clasped the rails are so secured that thesashes cannot rattle by the force of the wind,

thus obviating an annoyance not overcome by fasteners usually applied.

What I claim as my invention, and desire to secure by Letters Patent,is-- 1. In a sash-fastener, the section A, formed with the base a,upright or vertical wall I), with perforated lugs c 0 and interlockingarms (I d. extending from the under side of the lugs, substantially asdescribed.

2. In a sashfastener, the section A, formed with the base a, upright orvertical wall I), with perforated lugs c c, the interlocking arms (1 d,and the vertical recess 0, substantially as described.

3. In a sash-fastener, the gravity lockinghook constructed with the lugi, thumb-piece k, and side flanges, l, substantially as described.

GARY B. SMITH.
